Spatial and Temporal Analysis of Nighttime Lighting In and Around National Parks

Yu Chuan Shan, Ben Banet, and I have been working the past couple of years on developing a monthly database of upward radiance from within and buffers around all of the National Park units in the United States.  They are presenting the research today at the USC undergraduate research symposium.  The results presented only scratch … Continue reading Spatial and Temporal Analysis of Nighttime Lighting In and Around National Parks

Healthy Urbanism in Polluted Cities

  Colleagues at USC Environmental Health Centers are putting together a 1-day conference titled Parks, Pollution, and Obesity. I’ve been awarded a USC Architecture Graduate Research Scholar grant to work with this group to bridge between the public health researchers and landscape architects and urbanists. The premise is as follows. Awareness among landscape architects, urban … Continue reading Healthy Urbanism in Polluted Cities

Unintentional Media Blitz

As a result of the new atlas of of artificial night sky brightness I ended up doing a lot of interviews for national and international outlets, including Science Magazine, Takepart.com, Christian Science Monitor, Scientific American, and USA Today. Then the American Medical Association released a statement on LED lighting (for which I had provided some … Continue reading Unintentional Media Blitz

Predicting Continental-Scale Bird Migration Routes from Landscape Parameters

William Winters, one of my GIST students, successfully filed his MS thesis last fall, in which he created proof-of-concept models for bird migration routes at the continental scale.  We developed the topic as a way to fill in a missing scale in the efforts to reduce mortality of birds at towers and buildings.  At the … Continue reading Predicting Continental-Scale Bird Migration Routes from Landscape Parameters

Belowground interactions with aboveground consequences: Invasive earthworms and arbuscular mycorrhizal fungi

Shishir Paudel, Travis Longcore, Beau MacDonald, Melissa K. McCormick, Katalin Szlavecz, Gail W. T. Wilson,  and Scott R. Loss Ecology Volume 97, Issue 3, March 2016, Pages 605–614 Abstract.  A mounting body of research suggests that invasive nonnative earthworms substantially alter microbial communities, including arbuscular mycorrhizal fungi (AMF). These changes to AMF can cascade to affect plant communities and vertebrate populations. Despite these … Continue reading Belowground interactions with aboveground consequences: Invasive earthworms and arbuscular mycorrhizal fungi

Heading to New Orleans: Ecologically Sensitive Lighting Design

Landscape architects, mark your calendars.  I’ll be part of a joint presentation on Ecologically Sensitive Lighting Design that was just accepted to the American Society of Landscape Architects annual meeting in New Orleans this fall.  I teamed up with lighting designer Linnaea Tillett and lighting engineer Nancy Clanton, two of the top landscape lighting experts … Continue reading Heading to New Orleans: Ecologically Sensitive Lighting Design
